2 Connections to Chemistry, 16 October 2013 Energy: Now and Forever? The Industrial Revolution: A future of limitless human achievement? 1830 George Stephenson's locomotive, The Rocket "Watt and Stephenson whispered in the ear of mankind their secret, that a half ounce of coal will draw two tons a mile …" The Conduct of life, "Wealth" Ralph Waldo Emerson

3 The Industrial Revolution: A future of limitless human achievement? 2008 A modern diesel locomotive. Trains can move a ton of freight nearly 450 [revenue ton-] miles on a single gallon of fuel. CSX advertisement Energy: Now and Forever? Connections to Chemistry, 16 October 2013

4 Energy: Now and Forever? Connections to Chemistry, 16 October 2013 The Industrial Revolution: A future of limitless human achievement? Achievements unimagined by Emerson require unimaginable amounts of energy. What else was unimagined?

5 Connections to Chemistry, 16 October 2013 Energy: Now and Forever?  The concentration of atmospheric CO 2 is increasing, due mainly to the burning of fossil fuels.  Earth’s temperature increases as more CO 2 and other greenhouse gases enter the atmosphere.  Increasing temperature and CO 2 bring about changes in the Earth’s climate.

6 Connections to Chemistry, 16 October 2013 Energy: Now and Forever? What do you know about climate change? What would you like to know? What would your students like to know? What would your friends like to know?

8 Connections to Chemistry, 16 October 2013 Energy: Now and Forever? Ice is melting. Grinnell Glacier, Glacier Nat’l Park

9 Connections to Chemistry, 16 October 2013 Energy: Now and Forever? CO 2 has varied naturally over time. Human-caused change is larger and faster than any time in at least the past million years.

10 Connections to Chemistry, 16 October 2013 Energy: Now and Forever? Where is the global warming? Almost entirely in the oceans.

11 Connections to Chemistry, 16 October 2013 Energy: Now and Forever? Sea level is rising as glaciers and ice sheets melt and the oceans warm.

12 Connections to Chemistry, 16 October 2013 Energy: Now and Forever? Oceans dissolve CO 2 and become more acidic.

13 Connections to Chemistry, 16 October 2013 Energy: Now and Forever?

14 American Chemical Society The Industrial Revolution: A boon that enormously benefits man. The Industrial Revolution: A boon that comes with an enormous energy price tag mostly paid for in burning fossil fuel. The Industrial Revolution: A boon that comes with the unintended consequence that carbon emissions are changing the Earth's climate in disturbing ways. The Industrial Revolution: A boon that challenges the Watts and Stephensons of the 21 st century to develop ways to use energy more efficiently, to produce alternative non-carbon- emitting sources, and to reduce the impact of carbon-emitting sources. Energy: Now and Forever?

15 Connections to Chemistry, 16 October 2013 Energy: Now and Forever! Why understanding and teaching climate change are so important. Those future Watts and Stephensons are in your classrooms. Global climate change is a vital issue for life on Earth and involves many processes and concepts related to chemistry. Engaging with this issue in deliberative discourse requires understanding the fundamental science that determines Earth’s climate. See ACS Climate Science Toolkit available at As chemists and teachers, we have a responsibility to use our knowledge to communicate with others about climate change.

16 Connections to Chemistry, 16 October 2013 What's next?  Browse the Toolkit to see what can be useful to you.  Integrate climate change science in your regular course curriculum. See Science_of_Climate_Classroom.pptx.  Engage your friends and colleagues in deliberative discussion on the science of global climate change.  Set an example and encourage others to adopt personal choices that decrease the undesired consequences of climate change.  Take a public stand on the issues related to the undesired consequences of climate change and the need for mitigation and adaptation. Encourage and support your local and national governmental representatives to do the same. Energy: Now and Forever!
